Indeed, the St. Pete letter is outside the focus of this thread, i.e. the profile of the perps who actually mailed the anthrax.

I suspect you are right that they have found no prints. And I suppose if someone saw a person mailing letters wearing rubber gloves they would have come forward by now. I was hoping maybe the fingerprints of the mail carrier who first retrieved the letter from whatever mailbox it was mailed from might be found so that the site of the mailing could be better pinpointed.

Hmmm ... I wonder if they checked fingerprints on the letter to the carrier that they presumed was the one who picked up the letters early on??? The way it cross-contaminated so easily perhaps that initial infection clue was false.
